Abstract
An electro(stato)graphic method is provided, comprising the steps of image wise applying toner particles to a final substrate and fixing the toner particles on a final non-photoconductive substrate, characterized in that PA1 (i) the toner particles comprise at least one substantially light insensitive silver salt (compound B) and at least one reductant (compound A), so as to be capable, upon reaction of compound A and B, of forming a light absorbing substance in said final substrate, PA1 (ii) the toner particles optionally comprise a light absorbing pigment or dye PA1 (iii) the light absorbing substance can give a maximum density (D.sub.max)>2.00 either on itself or in combination with said light absorbing pigment or dye and PA1 (iv) the toner particles are fixed on to the final substrate by heat or by heat and pressure.
